[Periodontal response to orthodontic treatment].

Abstract

Monkeys bicuspids were subjected to experimental periodontitis inducing pockets with bifurcation involvement. Light continuous extrusive and intrusive forces were then applied on these bicuspids. The extrusive forces were applied on 3 monkeys; bone apposition was obtained. The intrusive forces were applied on 4 monkeys after pocket surgery and careful root surface scaling. A meticulous hygiene program was then maintained. In these conditions new attachment was gained through intrusion.
